By default, heatmaps are rendered at 1280px. You can view a heatmap at different viewport widths by selecting one of the predefined device sizes (Desktop, Tablet, or Mobile), or by choosing a Custom width from the dropdown.

To change the displayed resolution, use the controls at the top of the heatmap.
